Rashtriya Lok Dal (RLD) supremo and Civil Aviation Minister Ajit Singh on Sunday ruled out that it could tie up with the Samajwadi Party (SP) in Uttar Pradesh leaving it ally Congress amid exit poll reports putting SP as the single largest winner in the state. "It is a totally concocted story," said Singh referring to the news that RLD, which fought the elections in UP in alliance with the Congress, could switch sides. "We have an alliance with Congress, our alliance will continue, whatever we do will be in discussion with Congress," Singh told a news channel rubbishing the reports. Exit polls said Mulayam Singh and his son Akhilesh Yadav led Samajwadi Party will be the single largest winner in Uttar Pradesh where a seven phase politically charged election ended on Saturday. According to a Star News-AC Neilson exit poll, the SP will be the largest winner with 183 seats in the 404-member strong assembly. It will be followed by the Bahujan Samaj Party (BSP) with 83 seats.
